To all whom it may concern:

it lmcwnjihct 1, Lewis E. Moiemsorr, s 01(212163 of the United States of America, and.

is resident of the city of Newark, county of Essex, State oi New Jersey, have invented certsin he i and useful improvements 'in Sheetl ee-chg Mechanisms, of which thefollowing is e specificstion. V

The present invention relates to sheet feeding mechanisms for feeding sheets of paper to printing or other machines, and its olqect is to provide en sutometic feeding mechanism of improved and simple construction end operction and easily adapted to he 'ettsched to different types of machines without causing great changes to he made in their construction.

Broadly speslrm my invention comprises -e stationery table'- sdsptedto rcceive'thc sheets end s separating mechanism including o suction roller for sepsreting and feeding the sheet to the particular machine to which the {I 1 I 3 {I reed is attached, and means I01 the operation of the mechsnism.-

Hence the inyention'compri'ses such ele ments of construction and arrangement of parts as will be set forth in the following description end pointed out in the claims, while referring to the accompanying-drawings.

I desire it to he understood, however, that I consider myself entitled to such changes within the. limit and scope of the claims as will resdil suggest themselves to those skilled in tile srt.

In the said drawings Figure 1 is at side view showing my invention stteched to e machine,

- which only much is shown as is necesssry to the understanding of the operation my invention. Fig. 2 IS a. sectional View of the feedir mechemsm Fi f2 w o c low of i 2. e is on eolerged dew-cl 716W of the gearing and Fig. 5 is see ed View provi suction roller 11.

income of the tube 29. For this end the is e. plsn t he attached to any kind of I which will he described later, and the main rock-shaft 4, which carries the se crating and feeding mechenism proper. pen the said shalt e. is mounted two brackets 5, one at either end which are joined by the girts'or bars 6 end 7, and thus forms s framework for the separating and feeding elements.

' 8 indicates a. pile of sheets to be separated and fed, and 9 is the inclined stationery table orsu zlport for the said sheets. This tehleis ed with the usual guides and is fastenedto the machine by any suitable and convenient means such as brackets, 10.

In the rear of and adjacent to the table and the hreclretsfi is mounted the lhis suction roller come. centrel shaft 12 provided with a. ongitudinsleir passage 13, which extends from the'one cod and to the enlarged middle portion of the roller, where other rodiel air passe es l4. lead to the surface of the roller. 'lwos eeves 15 envelop the shsit 12 on either side of the enlerged portion, and the surfaces of the said sleeves are flush with the surfaces of the centrel portion. The longitudinal sir passage is connected to air pump 28 hv fol; lowing see Fig. 3. The sleeves are free to rotate ontheshsft and are held in place by means cl" collars 16. A gear 17 is carried feet on the shaft 12 by means of set screws 18 end coecting with the rock ill on the table 9.

Gears es 22 end are carried by the elicits of these two "-19 end 26 respectively. The bar 7 is 'ded with the seperetin'g lip or d zstsl -ly niountedhy means of slots 25 srrl screws 26, end on either side of 24 mounted at on an is thereto two stops 80 indicates 2. tabs or support on the s b!) hich the sheets are fed, to he by any suitehle mechllmism. In the sent instsnce 36 would indicate the registeririg tslolc on the press.

As already stated the shove described elements form the separating and feeding mechsnism proper, and i will now describe their functions end operation, endleter point out the roechsnicel eetusting devices.

tis of course hardly necessa to state that' my feeding mechanism osci ates once i means are merely shown as entirely 7 difierent, but

mechanic., 1 claim, vhowever,

might with anothe changes and variations within the spirit of the invention to which the scope of the claims entitle me. i

What I claim is:

I. In an automatic sheet separating de-' vice a rotatable suction roller having radial air passages of different sizes, a pro'ection on the surface of said roller adjacent t e largest size radial air passage, said projection extending in a direction op osite to the direcv -stantly in one direction,

tion of rotation of the sai roller.

2. In an automatic sheet separating device a rotatable suction rollerhaving radial air'passages of different sizes, a rejection adapted to aid in separating the owermost sheet, the surface oi tangent to the roller at the end of the axis of the adjacent air passage and extending in a direction opposite to the direction of rotation of said roller.

3. In ail-automatic sheet feeding device the. combination with a stationary table adapted to receive a pile of'sheets, a separating and feeding mechanism com rising a suction roller adapted to se arate t e lowermost sheet from the other s eets, radial air passages of different sizes in the said roller, a plurality of loose sleeves on the shaft of the said roller, a'plurality of guide or feed rollers, means for rotating the said feed rollers conthe said feed rollers said projection being being adapted to receive the sheet from the said suction roller, a sheet lifting device adapted to separate the said pile of sheets from the lowermost one, abut the leading edges of the thus separated sheets,- means tor oscillating the said separatingmechanism and means carried by the said table for oscillating the said suction roller independently from'the said mechanism.

4. In an automatic sheet separating device a rotatable suction roller, having radial air passages of different sizes in said roller, a--

said cam being for the purpose asset forth and located adjacent the largest size passage, the surface of said cam extendin in a direction op osite to the direction o rotation of said roller and substancam on said roller,

tially tangent to the roller at the end of the radial axis of the adjacent passage. 0

5. In an automatic sheet separating device a rotatable suction roller, having radial air passages of different sizes in said roller, a cam on the surface of said roller adjacent the largest size radial air passage, said cam extendin in a direction opposite to the direction 0% rotation of said roller, and means whereby any of the air passages may be brought into workingposition.

6. in an automatic sheet separating and feeding device the combination with a stationary table adapted to receive a ile of sheets, anosci'llating separating and ceding mechanism comprising a suction roller, having radial air passages of different sizes in said roller, a cam carried by said roller, guide or feedrollers adapted to receive the sheet from said suction roller, a sheet lifting device,fmeans for oscillating said mechanism and means roller independently from the said mechanism.
